Health guides
These twelve guides explain which blood tests are relevant for a given health concern, what each biomarker measures, and how to read the result.
Each one covers the markers we test in Sweden, the signs that testing is worthwhile, and what your values are likely to mean. You do not need a referral to order any of these tests.
Browse by health concern
Thyroid health →
TSH, Free T4, Free T3 and thyroid antibodies — what an under- or overactive thyroid looks like in blood.
Vitamin deficiency →
Vitamin D, B12, folate and minerals: which deficiencies are common in Sweden and how they are detected.
Hormone balance →
Cortisol, testosterone, oestradiol, progesterone, DHEA-S and SHBG, and when each is worth measuring.
Persistent fatigue →
The blood markers that explain long-term tiredness, from low ferritin to thyroid and blood sugar.
Iron deficiency →
Ferritin, transferrin saturation and haemoglobin — low iron long before it becomes anaemia.
Cholesterol and heart risk →
LDL, HDL, triglycerides and ApoB, and what they say about cardiovascular risk.
Blood sugar and diabetes risk →
Fasting glucose, HbA1c and insulin: spotting insulin resistance before it becomes diabetes.
Men's health →
Testosterone, PSA, metabolic and cardiovascular markers relevant to men at each stage of life.
Women's health →
Cycle, fertility, perimenopause and iron — the markers that matter across a woman's life.
Fitness and performance →
Recovery, muscle, iron status and inflammation markers for people who train seriously.
Children's health →
Iron, vitamin D, B12 and coeliac screening — deficiencies that show up as tiredness, poor concentration or low mood.
Healthspan and ageing →
ApoB, Lp(a), fasting insulin, cystatin C and IGF-1 — the markers that track ageing rather than current illness.
